SPECIFICATION forming part of Letters Patent No. 643,09i., dated February 6, i900..

Application filed September 20, 1899. Seriel'llo. 731.094. (No model.)

Be itknown that I, JOHN lV. HAYS', a citizen of the, United States, residing at Oklahoma City, in the county of Oklahoma and Territory of Oklahoma, have invented'certain new and useful Improvements in Nests for Poultry; andI do hereby declare the following to he a full, clear, and exact descripothers skilled in the' artto which it appertains to make and use the same.

This invention has relationy to nests for poultry, and is designed as an improvement upon the nest shown in my formel-application for Letters Patent, tiled J une 20, 1899, Serial No. 721,235, the object of the present invention being to provide a simplified structure having an improved automatic door adapted to close when the hen is in the nest` to preventv entrance ot' other hens thereto and to open when the hen leaves the nest.

For a full description of the' invention and the merits therot and also to acquire a knowledge of the details of construction of the means for edecting the result reference is to be had tothe following description and the drawings hereto attached.

While the essential and characteristic features of theinvention are necessarilysusceptiblev of modification, still the preferred om! bodiment is illustrated in the accompanyingl drawings, in whichl Figure 1 is a perspective View of a device constructed in accordance with and embodying ythe essential features of the invention.Y Fig. 2 is a view of the device inverted. Fig. 3 is avertical longitudinal section of the framework, 'showing' the operative parte `:in their normal positions with the door open for entrance of a hen. Fig. 4 is a similar view showing the relation of the parts when a hen is inthe nest.' Fig. 5 is a detail perspective 'view of the tilting platform andweight-box.

Fig. 6l is a bottom 'plan view of the nest. Fig.'7 is a detail perspective view of the gate and connections. a modified .form of gate and connections.

,Corresponding and. like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Fig. 8 is a similar view of The device comprises an iuclosurc l, in the form of a house or coop, the inclosiug sides or walls being composed ot' slats which are spaced apart for the purpose ot ventilation and the admission of light, besides providing a structure easily portable and` readily accessihle for the purpose of inspection and This framework or coop is provided in its front end with a door-opening 2 andin its 'top side with an opening closed by a door 3, which latter is hinged to swing up- 'lhis wardly and forwardly at its free end. door is located at `She rear end yot' the coop and directly over the nest, but may cover practically the entire top of the coop, and serves the double purpose oi protecting said nest from rain and admittingof access to tho nest for the removal of eggs laidthercin.

The nest 4 is located at the rear of the framework and comprises a shallow tray having its front and rear walls upwardly divergent and of a length to extend from one side wall of the coop to the other without touching either. This nest is mounted in the manner hereinafter described to have a slight tilting or rocking movemcntand is held in position and limited in suoli movement by supporting-rods 5, jointed at their lower ends to eyes i5 upon the forward portion of the nest and detachaloly connected at their upper ends tothe framework, and upon the under side of the nest journals or rocker-hearings 7 lare provided.

The tiltingr platform D is located inadlvance of the nest and is supported by means oi longitudinally-disposed sills l0, connected by transverse slats 9- and secured adjacent to their rear' ends to a cross-beam 1l, having its end portions reduced and forming journals l1, which `obtain bearings in notches l2, formed in the upper edgesof transverselyalining side slats. The longitudinal sills have reduced rear ends, forming arms 13, which extend beneath the nest, and are-further conthe nest being limited by the supporting-rods 5. The forwardpend of the platformf) is movable .vertically in a transverse opening S, formed in the front of the framework below the door-opening 2, and constitutes an ap- -proach to the nest and is weighted, so-asrto ditional weights therein or removing some of .the weights therefrom. '.lhe body ofthe box is formed by the front ends, of the sills 10, front and back cross-pieces 2f), and the slats 9 at the forward end of the platform, which are placed closelytogether to formrthc '.bottom of the box.

The door 1G is hinged or'pivoted at its upper end to a transverse shaft 2] mounted at the top of the door-opening 2, so as to swing outward and upward at its lower end, and has attached thereto or formed thereon inwardprojecting crank-arms 22. 'lhese arms are jointed to the upper ends of connecting-,rods 23, which-are in turn jointed at their lower ends to the forward end of the platform,` theI construction and arrangement being such that. the upward movement of the platform will cause the door .to close, while the downward movement thereof will draw upon the crank-arms to canse the door to swing outward and open. A trip 2-1- is applied to the platform at or near the rear end of the box l? and serves as a perch or rest upon which the hen alights in entering and leaving the nest. The upper end or platform of this trip,

t door 1G to close.

perch,or rest is normally disposed in the plane of the top of the nest, and the weight of the hen alighting thereon on leaving the nest is communicated thereby tothe platform, which tilts downward and forces the door open.

\As shown in Itig.- 1, the nest is ,normally A held elevated, the platform depressed, and

the door open. When a hen passes through .the door-openin g 2 and porches upon the nest,

the latter is depressed and the platform elevated, thereby forcing the connecting-rods 23 and crank-rods 22 upward and causing the As the hen leaves the nest ands'teps upon the perch or trip24 the platform will descendand force the door open through the medium of the eonnectionsafore- Said. At the same time that the front end of the platform lowers the nest will rise, thereby setting the device for the next hen, as will be readily understood. The eggs are removed from the nest through the opening closed by the door 3, as previously stated. e

. In Fig. S I have shown a modified construetion of swing-door lli, w lich is somewhat simpler in constructit'm and adapted to be more conveniently detached. 'lhe frame' of this door is formed of a piece of stout wire bent into U shape and thence extendedlaterally or at rightangles to said frame to provide the bearing-arms LG and to form the crank-arms 27, extending at right angles to said bearing-'arms and adapted for the attachment thereto of the connecting-rods 225. The open spaceof the door-frame thus constructed is closed by longitiulinal and transverse rods 'lhe bearing-arms 2li are journaled in open bearing-blocks f),secured tothe coop, and are confined therein by-pins 30, which may be removed whenever it is desired to detach the door.

llaving thus described the invention, what is claimed as new isl. In a nest, the combination of a easing or inelosing framework, a tilting platform ar- .ranged therein and ypivoted betweenits ends and provided with journals at its rear-end, supporting-rods connected to the casing, and a nest arranged above t he platform and jointed at. its top to saidA rods and provided on its under side with notched bearings engaging said journals, substantially as described.

2. In a nest, the eombinationof a easing or inelosing framework having a door-opening, a tilting platform arranged therein and pivoted between its ends and provided at its Vfront end with a closed box for the reception,

of weights and at its rear end with lower journals having bearing in the casing and'also with upper journals, a hinged door controlling said door-opening and comprisinga frame having crank-arms, connecting-rods jointed at their upper ends to said crank-arms and at their lower ends to said box, pendent snpporting-rods connected to the-easing at the rear thereof, and a nest arranged above thcplatform and jointed' at its top to said rods .and provided on its underside with notched bearings engaging said journals, substantially as described. y

In testimony whereof I affix my signature in presence of two witnesses.-
